The Perfect Clue

Mona Stewart, madcap, spoiled daughter of a wealthy man, becomes upset when she learns that her father is engaged to a woman she hates. She runs away, via various modes of transportation, and hires an ex-con, David Mannering, to drive her around as she eludes the all-out search conducted by her father and her fiancée, Ronnie Van Zandt. A romance is blossoming until her chauffeur is arrested for the murder of a crime-syndicate boss. (imdb)
